It's hard to tell from the photo but I would guess that you should not see any of the green EGC. Waste disposers are permitted to be cord and plug connected if they meet the requirements of the NEC in 422.16(B)(1). That means that the cord must be identified as suitable for the purpose. It's unclear if the cord in the photo is so identified. If you really wanted to nitpick that NM connector is probably not listed to be used with that cord.

422.16 Flexible Cords.
(B) Specific Appliances.
(1) Electrically Operated Kitchen Waste Disposers. Electrically operated kitchen waste disposers shall be permitted to be cord-and-plug-connected with a flexible cord identified as suitable for the purpose in the installation instructions of the appliance manufacturer, where all of the following conditions are met:
(1) The flexible cord shall be terminated with a grounding-type attachment plug.
Exception: A listed kitchen waste disposer distinctly marked to identify it as protected by a system of double insulation, or its equivalent, shall not be required to be terminated with a grounding-type attachment plug.
(2) The length of the cord shall not be less than 450 mm (18 in.) and not over 900 mm (36 in.).
(3) Receptacles shall be located to avoid physical damage to the flexible cord.
(4) The receptacle shall be accessible.
